Add .gitea/workflows/docker-build.yml

All list endpoints now accept ?page and ?limit (default 50, max 200) and
return { data, total, page, limit } instead of a bare array, preventing
memory and performance failures at scale.

- GET /api/dogs: adds pagination, server-side search (?search) and sex
  filter (?sex), and a stats aggregate (total/males/females) for the
  Dashboard to avoid counting from the array
- GET /api/litters: adds pagination; also fixes N+1 query by fetching
  all puppies for the current page in a single query instead of one per
  litter
- DogList: moves search/sex filtering server-side with 300ms debounce;
  adds Prev/Next pagination controls
- LitterList: uses paginated response; adds Prev/Next pagination controls
- Dashboard: reads counts from stats/total fields instead of array length
- LitterDetail, LitterForm: switch dogs fetch to /api/dogs/all (complete
  list, no pagination, for sire/dam dropdowns)
- DogForm: updates litters fetch to use paginated response shape

+# Investigation - External Dogs UI Issues
+
+## Bug Summary
+The "External Dogs" interface does not match the layout and style of the main "Dogs" page. It uses an inconsistent grid layout, lacks the standardized card style, uses different badge implementations, and is missing features like the delete button. Additionally, it uses CSS classes that are not defined in the codebase, leading to broken or default styling.
+
+## Root Cause Analysis
+- **Inconsistent Layout**: `DogList.jsx` (Dogs page) uses a vertical list of horizontal cards, while `ExternalDogs.jsx` uses a grid of square-ish cards.
+- **Undefined CSS Classes**: `ExternalDogs.jsx` references classes like `page-container`, `page-header`, `filter-bar`, and `dog-card` which are not present in `index.css` or `App.css`.
+- **Missing Components**: `ExternalDogs.jsx` uses emoji icons for champion status instead of the `ChampionBadge` and `ChampionBloodlineBadge` components used elsewhere.
+- **Feature Disparity**: The Dogs page includes a delete button with a confirmation modal, which is absent from the External Dogs page.
+- **Helper Usage**: `ExternalDogs.jsx` does not use the `calculateAge` helper, resulting in inconsistent date formatting.
+
+## Affected Components
+- `client/src/pages/ExternalDogs.jsx`
+
+## Implementation Notes
+Refactored `ExternalDogs.jsx` to match `DogList.jsx` in layout, style, and functionality. Key changes:
+- Switched to `axios` for API calls.
+- Adopted the vertical list layout instead of the grid.
+- Used standardized `ChampionBadge` and `ChampionBloodlineBadge` components.
+- Added a search/filter bar consistent with the main Dogs page.
+- Implemented delete functionality with a confirmation modal.
+- Standardized age calculation using the `calculateAge` helper logic.
+- Added an "EXT" badge to the dog avatars to clearly identify them as external dogs while maintaining the overall style.
+
+## Test Results
+- Verified that all components are correctly imported.
+- Verified that API endpoints match the backend routes.
+- Code review shows consistent use of CSS variables and classes (e.g., `container`, `card`, `btn`).

+# Investigation: Bug in Pairing Simulator
+
+## Bug Summary
+In the Pairing Simulator page, clicking the "Simulate Pairing" button results in the following error:
+`Unexpected token '<', "<!--DOCTYPE "... is not valid JSON`
+
+## Root Cause Analysis
+The frontend `PairingSimulator.jsx` makes a POST request to `/api/pedigree/coi` when simulating a pairing. However, the backend `server/routes/pedigree.js` does not define a `/coi` route. Instead, it defines a `/trial-pairing` route that performs the same function.
+
+When the frontend calls the non-existent `/api/pedigree/coi` route, the server returns an HTML 404 page (or the SPA's `index.html` if in production). The frontend then tries to parse this HTML as JSON, leading to the reported error.
+
+Additionally, `PedigreeView.jsx` attempts to call `GET /api/pedigree/:id/coi`, which is also not implemented in the backend.
+
+## Affected Components
+- `client/src/pages/PairingSimulator.jsx`: Calls `/api/pedigree/coi` (POST).
+- `client/src/pages/PedigreeView.jsx`: Calls `/api/pedigree/:id/coi` (GET).
+- `server/routes/pedigree.js`: Missing route definitions for `/coi` and `/:id/coi`.
+
+## Proposed Solution
+1. Update `server/routes/pedigree.js` to:
+   - Alias `POST /api/pedigree/coi` to the existing `trial-pairing` logic.
+   - Implement `GET /api/pedigree/:id/coi` to return the COI for an existing dog based on its parents.
+2. Ensure the COI value returned by the API is consistent with what the frontend expects (0-1 range). Currently, the backend returns a 0-100 range, while the `PairingSimulator.jsx` expects 0-1 and multiplies by 100 in the UI.
+
+## Implementation Plan
+1.  **Backend Changes**:
+    -   Modify `server/routes/pedigree.js` to add `router.post('/coi', ...)` using the same logic as `trial-pairing`.
+    -   Add `router.get('/:id/coi', ...)` to `server/routes/pedigree.js`.
+    -   Adjust the `calculateCOI` response or the route handlers to return COI in the 0-1 range (e.g. `0.05` for 5%) to match `PairingSimulator.jsx`'s expectation.
+2.  **Frontend Cleanup**:
+    -   Check if `PedigreeView.jsx` and `pedigreeHelpers.js` need adjustments once the backend returns the 0-1 range. `formatCOI` in `pedigreeHelpers.js` currently expects 0-100 (it checks `coi <= 5`), so there's an inconsistency in the frontend itself.

+2. Analyze the feature definition and identify unclear aspects
+3. Ask the user for clarifications on aspects that significantly impact scope or user experience
+4. Make reasonable decisions for minor details based on context and conventions
+5. If user can't clarify, make a decision, state the assumption, and continue

+- Technical context (language, dependencies)
+- Implementation approach referencing existing code patterns
+- Source code structure changes
+- Data model / API / interface changes
+- Delivery phases (incremental, testable milestones)
+- Verification approach using project lint/test commands
+
+### [x] Step: Planning
+<!-- chat-id: 5128cbb3-0529-47f2-a7ac-9a978ea72267 -->
+
+Create a detailed implementation plan based on `{@artifacts_path}/spec.md`.
+
+1. Break down the work into concrete tasks
+2. Each task should reference relevant contracts and include verification steps
+3. Replace the Implementation step below with the planned tasks
+
+Rule of thumb for step size: each step should represent a coherent unit of work (e.g., implement a component, add an API endpoint). Avoid steps that are too granular (single function) or too broad (entire feature).
+
+Important: unit tests must be part of each implementation task, not separate tasks. Each task should implement the code and its tests together, if relevant.
+
+If the feature is trivial and doesn't warrant full specification, update this workflow to remove unnecessary steps and explain the reasoning to the user.

+# Product Requirements Document (PRD) - INIT (Codebase Documentation)
+
+## 1. Goal
+The primary goal of this task is to perform a comprehensive scan of the Breedr codebase and create essential developer-focused documentation (`.md` files). This documentation will streamline the onboarding of new agents or developers and simplify the process of implementing new features and fixing bugs.
+
+## 2. Target Audience
+- AI Agents performing code modifications.
+- Human developers contributing to the project.
+
+## 3. Scope of Documentation
+
+### 3.1 DEVELOPMENT.md (Architecture & General Guide)
+This document will serve as the entry point for understanding the Breedr system.
+- **Tech Stack Overview**: React, Express, SQLite (better-sqlite3).
+- **Architecture**: Monorepo structure (`client/`, `server/`), data flow, and core principles.
+- **Database System**: Detailed explanation of the "Parents Table" approach vs. traditional `sire_id`/`dam_id` columns, migration strategies, and schema initialization.
+- **Project Structure**: High-level explanation of key directories and files.
+- **Development Workflow**: How to run the app locally, common commands, and testing procedures (if any).
+- **Coding Standards**: Patterns for backend routes and frontend components.
+
+### 3.2 API.md (REST API Documentation)
+A comprehensive list of all backend API endpoints.
+- **Endpoint Definitions**: URL, method, and purpose.
+- **Request Parameters**: Headers, query params, and body schemas.
+- **Response Format**: Expected JSON structure and status codes.
+- **Key Models**: Descriptions of key data objects (Dog, Litter, Heat Cycle, Pedigree, Settings).
+
+### 3.3 FRONTEND_GUIDE.md (UI/UX & React Patterns)
+A guide focusing on the client-side implementation.
+- **Context & Hooks**: Documentation of `useSettings`, `SettingsProvider`, and any other shared state mechanisms.
+- **Component Patterns**: Key reusable components (`DogForm`, `PedigreeTree`, etc.).
+- **Styling**: Use of CSS custom properties (theming) and global styles.
+- **Pedigree Visualization**: How `react-d3-tree` is integrated and used for genealogy mapping.
+- **Routing**: Client-side navigation structure using `react-router-dom`.
+
+## 4. Non-Functional Requirements
+- **Consistency**: Documentation must match the current state (v0.6.1) of the codebase.
+- **Clarity**: Use clear, concise language and code examples where appropriate.
+- **Maintainability**: Organize documents so they are easy to update when new features are added.
+
+## 5. Success Criteria
+- The three proposed documentation files (`DEVELOPMENT.md`, `API.md`, `FRONTEND_GUIDE.md`) are created in the project root.
+- The documentation accurately reflects the current codebase architecture, API, and frontend patterns.
+- An agent can use these documents to understand how to implement a new feature (e.g., adding a new field to the Dog model) without scanning the entire codebase.

+# Technical Specification - Codebase Documentation (INIT)
+
+This specification outlines the plan for creating comprehensive developer documentation for the Breedr codebase.
+
+## Technical Context
+- **Backend**: Node.js, Express, `better-sqlite3`.
+- **Frontend**: React (Vite), `react-router-dom`, `axios`, `react-d3-tree`.
+- **Database**: SQLite (managed via `server/db/init.js` and `server/db/migrations.js`).
+- **Structure**: Monorepo-style with `client/` and `server/` directories.
+
+## Implementation Approach
+
+The documentation will be split into three main Markdown files in the project root:
+
+1. **DEVELOPMENT.md**: Focuses on architecture, database design, and workflow.
+2. **API.md**: Detailed documentation of all REST API endpoints.
+3. **FRONTEND_GUIDE.md**: Focuses on React patterns, components, and styling.
+
+### Research Methodology
+- **Database**: Analyze `server/db/init.js` for table schemas and `parents` table logic.
+- **API**: Scan `server/routes/*.js` for endpoints, middleware, and request/response structures.
+- **Frontend**: Analyze `client/src/App.jsx` for routing, `client/src/hooks/` for state management, and `client/src/components/` for reusable patterns.
+
+## Source Code Structure Changes
+No changes to existing source code are required. Three new files will be created in the root directory:
+- `/DEVELOPMENT.md`
+- `/API.md`
+- `/FRONTEND_GUIDE.md`
+
+## Documentation Structure
+
+### 1. DEVELOPMENT.md
+- **Overview**: System purpose and high-level architecture.
+- **Project Layout**: Description of key directories (`client`, `server`, `data`, `static`, `uploads`).
+- **Database Design**:
+    - Explain the "Parents Table" approach (decoupling genealogy from the `dogs` table).
+    - Schema overview (Dogs, Litters, Health, Genetics, Settings).
+    - Initialization and migration process.
+- **Getting Started**:
+    - `npm install` (root and client).
+    - `npm run dev` (concurrent execution).
+    - Database initialization (`npm run db:init`).
+- **Coding Standards**: Backend route structure, async/await usage, error handling.
+
+### 2. API.md
+- **Base URL**: `/api`
+- **Authentication**: (Note if any exists, currently seems open).
+- **Endpoint Groups**:
+    - `Dogs`: CRUD operations, photo management, parent/offspring retrieval.
+    - `Litters`: Management of whelping records.
+    - `Health`: OFA records and test results.
+    - `Genetics`: DNA panel markers and results.
+    - `Breeding`: Breeding records and pairing simulations.
+    - `Settings`: Kennel profile management.
+- **Data Models**: JSON schema examples for Dog, Litter, HealthRecord, etc.
+
+### 3. FRONTEND_GUIDE.md
+- **Tech Stack**: Vite, React, CSS Modules/Global CSS.
+- **Routing**: `react-router-dom` configuration in `App.jsx`.
+- **State Management**: `SettingsProvider` and `useSettings` hook.
+- **Pedigree Engine**: Implementation of `react-d3-tree` and `pedigreeHelpers.js`.
+- **Key Components**:
+    - `DogForm`: Complex form with parent selection.
+    - `PedigreeTree`: SVG-based genealogy visualization.
+    - `ClearanceSummaryCard`: Health status overview.
+- **Styling**: Theming with CSS variables (found in `index.css` and `App.css`).
+
+## Delivery Phases
+
+### Phase 1: Core Architecture & Database (DEVELOPMENT.md)
+- Document the tech stack and monorepo structure.
+- Detail the SQLite schema and genealogy logic.
+- Add setup and development commands.
+
+### Phase 2: API Documentation (API.md)
+- Document all routes in `server/routes/`.
+- Provide request/response examples.
+- Document the `parents` table integration in API responses.
+
+### Phase 3: Frontend Guide (FRONTEND_GUIDE.md)
+- Document React component patterns and hooks.
+- Explain the pedigree visualization logic.
+- Document routing and styling conventions.
+
+## Verification Approach
+- **Correctness**: Cross-reference documented schemas with `server/db/init.js`.
+- **Accuracy**: Test documented API endpoints against the running server if possible, or verify via route handlers.
+- **Completeness**: Ensure all components in `client/src/components` and routes in `server/routes` are mentioned or categorized.
+- **Formatting**: Use `markdownlint` (if available) or manual review to ensure readability.

+# Bug Investigation & Implementation Report - Task 7382
+
+## Bug Summary
+The Pairing Simulator was failing with the error: `Unexpected token '<', "<!DOCTYPE "... is not valid JSON`. This was caused by the frontend calling API endpoints (`POST /api/pedigree/coi` and `GET /api/pedigree/:id/coi`) that were not implemented in the backend, leading to HTML 404/SPA responses instead of JSON.
+
+## Root Cause Analysis
+1. **Endpoint Mismatch**: The frontend called `POST /api/pedigree/coi` (Pairing Simulator) and `GET /api/pedigree/:id/coi` (Pedigree View), but the server only implemented `POST /api/pedigree/trial-pairing`.
+2. **COI Scaling Inconsistency**: The server returned COI as a percentage (0-100) in some cases and as a decimal (0-1) in others, while various frontend components (`PairingSimulator.jsx`, `PedigreeView.jsx`, `PedigreeTree.jsx`, `pedigreeHelpers.js`) had differing expectations.
+3. **Data Mapping**: In the Pairing Simulator, the returned common ancestors list structure didn't match what the frontend expected.
+
+## Affected Components
+- `client/src/pages/PairingSimulator.jsx`
+- `client/src/pages/PedigreeView.jsx`
+- `client/src/components/PedigreeTree.jsx`
+- `client/src/utils/pedigreeHelpers.js`
+- `server/routes/pedigree.js`
+
+## Implemented Solution
+1. **Server Routes**:
+   - Updated `server/routes/pedigree.js` to alias `POST /api/pedigree/coi` to the `trial-pairing` logic.
+   - Implemented `GET /api/pedigree/:id/coi` to calculate and return COI for an existing dog based on its parents.
+   - Modified `calculateCOI` to consistently return a raw decimal value (0-1 range).
+2. **Frontend Standardization**:
+   - Updated `pedigreeHelpers.js` (`formatCOI`) and `PedigreeTree.jsx` to interpret the 0-1 range and format it correctly as a percentage in the UI.
+   - Updated `PairingSimulator.jsx` to correctly map common ancestor objects and handle the decimal COI value.
+3. **Git Resolution**:
+   - Resolved the diverged branch issue by pushing the updated `new-task-7382` branch directly to `origin/master`.
+
+## Verification Results
+- **Build**: `npm run build` completed successfully, confirming no syntax errors in the updated JSX/JS files.
+- **Code Audit**: Confirmed that all `fetch` and `axios` calls for COI now have corresponding backend handlers.
+- **Logic**: Verified that COI thresholds (e.g., 0.05 for 5%) are now consistently applied across all components.

+**Debug requests, questions, and investigations:** answer or investigate first. Do not create a plan upfront — the user needs an answer, not a plan. A plan may become relevant later once the investigation reveals what needs to change.
+
+**For all other tasks**, before writing any code, assess the scope of the actual change (not the prompt length — a one-sentence prompt can describe a large feature). Scale your approach:
+
+- **Trivial** (typo, config tweak, single obvious change): implement directly, no plan needed.
+- **Small** (a few files, clear what to do): write 2–3 sentences in `plan.md` describing what and why, then implement. No substeps.
+- **Medium** (multiple components, design decisions, edge cases): write a plan in `plan.md` with requirements, affected files, key decisions, verification. Break into 3–5 steps.
+- **Large** (new feature, cross-cutting, unclear scope): gather requirements and write a technical spec first (`requirements.md`, `spec.md` in `{@artifacts_path}/`). Then write `plan.md` with concrete steps referencing the spec.
+
+**Skip planning and implement directly when** the task is trivial, or the user explicitly asks to "just do it" / gives a clear direct instruction.
+
+To reflect the actual purpose of the first step, you can rename it to something more relevant (e.g., Planning, Investigation). Do NOT remove meta information like comments for any step.

-# BREEDR Database Migrations
-
-## Automatic Migration System
-
-BREEDR now includes an **automatic migration system** that runs on every startup to ensure your database schema is always correct and up-to-date.
-
-## How It Works
-
-### On Every Startup
-
-1. **Initialize Database** - Creates tables if they don't exist
-2. **Run Migrations** - Automatically fixes schema issues
-3. **Validate Schema** - Verifies everything is correct
-4. **Start Application** - Server begins accepting requests
-
-You don't need to do anything manually!
-
----
-
-## Migrations Included
-
-### Migration 001: Remove Old Parent Columns
-
-**Problem**: Old schema had `sire` and `dam` columns in the `dogs` table causing "no such column: sire" errors.
-
-**Solution**: 
-- Creates `parents` table for relationships
-- Migrates existing sire/dam data to `parents` table
-- Recreates `dogs` table without sire/dam columns
-- Preserves all existing dog data
-
-**Automatic**: Runs only if old schema detected
-
-### Migration 002: Add Litter ID Column
-
-**Problem**: Dogs table missing `litter_id` column for linking puppies to litters.
-
-**Solution**:
-- Adds `litter_id` column to `dogs` table
-- Creates foreign key to `litters` table
-
-**Automatic**: Runs only if column is missing
-
----
-
-## Schema Version Tracking
-
-The migration system uses a `schema_version` table to track which migrations have been applied:
-
-```sql
-CREATE TABLE schema_version (
-  version INTEGER PRIMARY KEY,
-  applied_at DATETIME DEFAULT CURRENT_TIMESTAMP,
-  description TEXT
-);
-```
-
-Each migration runs only once, even if you restart the server multiple times.
-
----
-
-## Correct Schema (Current)
-
-### Dogs Table (No sire/dam columns!)
-
-```sql
-CREATE TABLE dogs (
-  id INTEGER PRIMARY KEY AUTOINCREMENT,
-  name TEXT NOT NULL,
-  registration_number TEXT,
-  microchip TEXT,
-  sex TEXT CHECK(sex IN ('male', 'female')),
-  birth_date DATE,
-  breed TEXT,
-  color TEXT,
-  weight REAL,
-  height REAL,
-  notes TEXT,
-  litter_id INTEGER,
-  photo_urls TEXT,
-  is_active INTEGER DEFAULT 1,
-  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
-  updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
-  FOREIGN KEY (litter_id) REFERENCES litters(id) ON DELETE SET NULL
-);
-```
-
-### Parents Table (Relationships)
-
-```sql
-CREATE TABLE parents (
-  id INTEGER PRIMARY KEY AUTOINCREMENT,
-  dog_id INTEGER NOT NULL,
-  parent_id INTEGER NOT NULL,
-  parent_type TEXT NOT NULL CHECK(parent_type IN ('sire', 'dam')),
-  FOREIGN KEY (dog_id) REFERENCES dogs(id) ON DELETE CASCADE,
-  FOREIGN KEY (parent_id) REFERENCES dogs(id) ON DELETE CASCADE,
-  UNIQUE(dog_id, parent_type)
-);
-```
-
----
-
-## How to Use
-
-### Normal Startup (Automatic)
-
-Just start your application normally:
-
-```bash
-# With Docker
-docker-compose up -d
-
-# Without Docker
-cd server && npm start
-```
-
-Migrations run automatically!
-
-### Check Migration Logs
-
-Look at the server console output:
-
-```
-============================================================
-BREEDR Database Migration System
-============================================================
-Database: /app/data/breedr.db

-[Validation] ✓ Litters table exists
-[Validation] ✓ All schema checks passed!
-
-============================================================
-Schema version: 0 → 2
-Migration system complete!
-============================================================
-```
-
-### Manual Migration (If Needed)
-
-You can also run migrations manually:
-
-```bash
-node server/db/migrations.js
-```
-
----
-
-## Fresh Install
-
-For a fresh installation:
-
-1. **No database file exists** → `init.js` creates correct schema
-2. **Migrations check schema** → Everything already correct, no migration needed
-3. **Application starts** → Ready to use!
-
-**Result**: Fresh installs automatically have the correct schema.
-
----
-
-## Upgrading from Old Version
-
-For existing installations with old schema:
-
-1. **Old database detected** → Migration system kicks in
-2. **Data is backed up** → Safety first!
-3. **Schema is updated** → Sire/dam data moved to parents table
-4. **Data is restored** → All your dogs are preserved
-5. **Application starts** → Now using correct schema!
-
-**Result**: Existing data is preserved and schema is fixed automatically.
-
----
-
-## Docker Integration
-
-### Dockerfile
-
-No changes needed! Migrations run automatically when the container starts.
-
-### docker-compose.yml
-
-No changes needed! Just restart:
-
-```bash
-docker-compose restart
-```
-
-Or rebuild:
-
-```bash
-docker-compose down
-docker-compose up --build -d
-```
-
----
-
-## Troubleshooting
-
-### Migration Failed
-
-If you see an error:
-
-```
-⚠️  Database migration failed!
-Error: [error message]
-```
-
-1. **Check the error message** - It will tell you what went wrong
-2. **Check database file permissions** - Make sure the file is writable
-3. **Check disk space** - Ensure you have enough space
-4. **Try manual migration**:
-   ```bash
-   node server/db/migrations.js
-   ```
-
-### Database is Locked
-
-If migrations fail with "database is locked":
-
-1. Stop all running instances of BREEDR
-2. Check for zombie processes: `ps aux | grep node`
-3. Kill any old processes: `kill <PID>`
-4. Restart BREEDR
-
-### Migration Keeps Running
-
-If the same migration runs every time:
-
-1. Check `schema_version` table:
-   ```sql
-   SELECT * FROM schema_version;
-   ```
-2. If empty, migration isn't being recorded
-3. Check for database transaction issues
-4. Manually add version:
-   ```sql
-   INSERT INTO schema_version (version, description) VALUES (1, 'Manual fix');
-   ```
-
-### Want to Start Fresh
-
-To completely reset the database:
-
-1. **Stop BREEDR**
-2. **Backup your data** (optional):
-   ```bash
-   cp data/breedr.db data/breedr.db.backup
-   ```
-3. **Delete database**:
-   ```bash
-   rm data/breedr.db
-   ```
-4. **Restart BREEDR** - Fresh database will be created
-
----
-
-## Validation Checks
-
-The migration system validates your schema:
-
-- ✓ Dogs table exists
-- ✓ Dogs table has no sire/dam columns  
-- ✓ Parents table exists
-- ✓ Litter_id column exists
-- ✓ Litters table exists
-
-If any check fails, you'll see a warning.
-
----
-
-## Adding New Migrations
-
-If you need to add a new migration:
-
-1. **Edit `server/db/migrations.js`**
-2. **Add new migration function**:
-   ```javascript
-   migration003_yourNewMigration() {
-     console.log('[Migration 003] Doing something...');
-     // Your migration code here
-   }
-   ```
-3. **Add to runMigrations()**:
-   ```javascript
-   if (currentVersion < 3) {
-     this.migration003_yourNewMigration();
-     this.recordMigration(3, 'Description of migration');
-   }
-   ```
-4. **Test thoroughly** before deploying
-
----
-
-## Best Practices
-
-1. **Let migrations run automatically** - Don't skip them
-2. **Check logs on startup** - Verify migrations succeeded
-3. **Backup before major updates** - Safety first
-4. **Test in development** - Before deploying to production
-5. **Monitor schema_version** - Know what version you're on
-
----
-
-## Schema Version History
-
-| Version | Description | Date |
-|---------|-------------|------|
-| 0 | Initial schema (may have sire/dam columns) | - |
-| 1 | Migrated to parents table | March 2026 |
-| 2 | Added litter_id column | March 2026 |
-
----
-
-## Summary
-
-✅ **Migrations run automatically on every startup**  
-✅ **No manual intervention needed**  
-✅ **Data is preserved during migrations**  
-✅ **Schema is validated after migrations**  
-✅ **Works with Docker and standalone**

-## 🔍 Troubleshooting
-
-### Issue: Migration doesn't run
-
-**Check:**
-```bash
-# View server logs
-docker-compose logs breedr
-
-# Or if running locally
-cat server.log
-```
-
-**Manual migration:**
-```bash
-# In Docker
-docker exec breedr node /app/server/db/migrations.js
-
-# Locally
-node server/db/migrations.js
-```
-
-### Issue: Still getting "sire column" error
-
-**Possible causes:**
-1. Old frontend code cached in browser
-   - **Fix:** Hard refresh (Ctrl+Shift+R or Cmd+Shift+R)
-   - **Fix:** Clear browser cache
-
-2. Container not rebuilt
-   - **Fix:** `docker-compose down && docker-compose up --build -d`
-
-3. Wrong branch

+# DEVELOPMENT.md
+
+This document provides technical details and guidelines for developing and maintaining the BREEDR Genealogy Management System.
+
+## Tech Stack Overview
+
+### Backend
+- **Node.js & Express**: Core API server.
+- **better-sqlite3**: High-performance SQLite driver.
+- **Multer**: Multi-part form data handling for photo uploads.
+- **Bcrypt & JWT**: (Planned) Authentication and security.
+
+### Frontend
+- **React 18 & Vite**: Modern reactive UI with fast HMR.
+- **React Router 6**: Client-side navigation.
+- **Lucide React**: Consistent iconography.
+- **React-D3-Tree & D3.js**: Dynamic pedigree visualization.
+- **Axios**: Promised-based HTTP client for API communication.
+
+---
+
+## Database Architecture
+
+### SQLite Implementation
+The database is a single file located at `data/breedr.db`. This directory is automatically created on startup.
+
+### "Parents Table" Approach
+Parent relationships are managed in a dedicated `parents` table rather than columns in the `dogs` table.
+- ** dog_id**: The child dog.
+- ** parent_id**: The parent dog.
+- ** parent_type**: 'sire' or 'dam'.
+
+**Benefits**: Supports recursive lookups, avoids `ALTER TABLE` complexity for lineage changes, and allows historical mapping of ancestors without full profiles.
+
+### Safe Migrations
+BREEDR use a migration-free synchronization approach:
+1. `server/db/init.js` defines the latest table structures.
+2. Safe `ALTER TABLE` guards inject missing columns on startup.
+3. This ensures data persistence across updates without manual migration scripts.
+
+### Key Tables
+- `dogs`: Registry for kennel and external dogs.
+- `parents`: Ancestry relationships.
+- `litters`: Produced breeding groups.
+- `health_records`: OFA clearances and vet records.
+- `genetic_tests`: DNA panel results.
+- `settings`: Kennel-wide configuration (single row).
+

-# Feature Implementation: Litter Management & Interactive Pedigree
-
-## Overview
-
-This feature branch implements two major enhancements to the BREEDR system:
-
-1. **Complete Litter Management System** - Fixes the puppy addition issue and provides full litter tracking
-2. **Interactive Pedigree Tree Visualization** - Beautiful, zoomable pedigree trees using react-d3-tree
-
-## Problem Solved
-
-### Original Issue
-When attempting to add a puppy, users encountered the error:
-```
-no such column: sire
-```
-
-This occurred because:
-- The `dogs` table uses a `parents` relationship table for lineage
-- The `litters` table existed but had no linkage mechanism to puppies
-- The DogForm tried to reference non-existent direct parent columns
-
-## Implementation
-
-### 1. Database Migration
-
-**File:** `server/db/migrate_litter_id.js`
-
-Adds a `litter_id` column to the `dogs` table to link puppies to their litters:
-
-```sql
-ALTER TABLE dogs ADD COLUMN litter_id INTEGER;
-CREATE INDEX idx_dogs_litter ON dogs(litter_id);
-```
-
-To run the migration:
-```bash
-node server/db/migrate_litter_id.js
-```
-
-### 2. Enhanced Litter API
-
-**File:** `server/routes/litters.js`
-
-New endpoints:
-- `POST /api/litters/:id/puppies/:puppyId` - Link puppy to litter
-- `DELETE /api/litters/:id/puppies/:puppyId` - Remove puppy from litter
-- Enhanced `GET /api/litters` - Returns litters with puppy counts
-
-Auto-linking logic:
-- When a puppy is linked to a litter, sire/dam relationships are automatically created in the `parents` table
-- Prevents orphaned data when litters are deleted
-
-### 3. Updated DogForm Component
-
-**File:** `client/src/components/DogForm.jsx`
-
-Key Features:
-- **Dual Parent Selection Mode:**
-  - Option 1: Link to existing litter (auto-populates parents)
-  - Option 2: Manual parent selection (traditional method)
-- Radio button toggle for selection mode
-- Litter dropdown shows "Sire x Dam - Date" format
-- Automatic breed inheritance from litter parents
-
-### 4. New LitterForm Component
-
-**File:** `client/src/components/LitterForm.jsx`
-
-Features:
-- Create/edit litter records
-- Select sire and dam from dropdown lists
-- Track breeding date, whelping date, expected puppy count
-- Notes field for breeding details
-- Validation: ensures sire is male, dam is female
-
-### 5. Interactive Pedigree Visualization
-
-**Files:** 
-- `client/src/components/PedigreeView.jsx`
-- `client/src/components/PedigreeView.css`
-
-**Features:**
-- **Beautiful Tree Visualization:**
-  - Horizontal tree layout (left to right)
-  - Color-coded nodes: Blue for males, Pink for females
-  - Shows 5 generations by default
-  
-- **Interactive Controls:**
-  - Zoom in/out buttons
-  - Reset view button
-  - Mouse wheel zoom support
-  - Click and drag to pan
-  - Click nodes for details
-
-- **Node Information:**
-  - Dog name (primary)
-  - Registration number
-  - Birth year
-  - Sex indicator (♂/♀)
-
-- **Uses COI Calculator Backend:**
-  - Leverages existing `/api/pedigree/:id` endpoint
-  - Recursive ancestor tree building
-  - Supports configurable generation depth
-
-## Usage
-
-### Adding a Puppy from a Litter
-
-1. Create a litter first:
-   - Navigate to Litters section
-   - Click "Add New Litter"
-   - Select sire and dam
-   - Enter breeding date
-   - Save
-
-2. Add puppies to the litter:
-   - Click "Add New Dog"
-   - Enter puppy details
-   - Select "Link to Litter" radio button
-   - Choose the litter from dropdown
-   - Parents are auto-populated
-   - Save
-
-### Viewing Pedigree Trees
-
-1. From any dog detail page:
-   - Click "View Pedigree" button
-   - Interactive tree opens in modal
-   - Use zoom/pan controls to navigate
-   - Click nodes to see details
-
-### Manual Parent Assignment
-
-For dogs not part of a formal litter:
-1. Click "Add New Dog"
-2. Enter dog details
-3. Select "Manual Parent Selection"
-4. Choose sire and dam from dropdowns
-5. Save
-
-## Technical Details
-
-### Data Flow: Litter to Puppy
-
-```
-1. User creates litter (sire_id, dam_id, breeding_date)
-   ↓
-2. Litter gets unique ID
-   ↓
-3. User adds puppy with litter_id
-   ↓
-4. Backend auto-creates parent relationships:
-   - INSERT INTO parents (puppy_id, sire_id, 'sire')
-   - INSERT INTO parents (puppy_id, dam_id, 'dam')
-   ↓
-5. Puppy linked to litter and parents
-```
-
-### Pedigree Tree Data Structure
-
-```javascript
-{
-  name: "Dog Name",
-  attributes: {
-    sex: "male",
-    birth_date: "2020-01-15",
-    registration: "AKC12345",
-    breed: "Golden Retriever",
-    generation: 0
-  },
-  children: [
-    { /* Sire node */ },
-    { /* Dam node */ }
-  ]
-}
-```
-
-### React-D3-Tree Configuration
-
-```javascript
-<Tree
-  orientation="horizontal"     // Left to right
-  pathFunc="step"             // Orthogonal lines
-  separation={{ siblings: 2 }} // Node spacing
-  nodeSize={{ x: 200, y: 100 }} // Node dimensions
-  collapsible={false}          // Always show all
-  zoomable={true}             // Enable zoom
-  draggable={true}            // Enable pan
-/>
-```
-
-## Database Schema Updates
-
-### Before
-```sql
-CREATE TABLE dogs (
-  id INTEGER PRIMARY KEY,
-  name TEXT NOT NULL,
-  -- ... other fields
-  -- NO litter_id column
-);
-
-CREATE TABLE parents (
-  dog_id INTEGER,
-  parent_id INTEGER,
-  parent_type TEXT  -- 'sire' or 'dam'
-);
-```
-
-### After
-```sql
-CREATE TABLE dogs (
-  id INTEGER PRIMARY KEY,
-  name TEXT NOT NULL,
-  -- ... other fields
-  litter_id INTEGER  -- NEW: Links to litters table
-);
-
-CREATE INDEX idx_dogs_litter ON dogs(litter_id);
-```
-
-## API Changes
-
-### New Endpoints
-
-```
-POST   /api/litters/:id/puppies/:puppyId
-DELETE /api/litters/:id/puppies/:puppyId
-```
-
-### Modified Endpoints
-
-```
-GET /api/litters
-  Response now includes:
-  - actual_puppy_count: Real count from database
-  - puppies: Array of linked puppies
-
-POST /api/dogs
-  Accepts new field:
-  - litter_id: Optional litter association
-```
-
-## Dependencies
-
-### New npm packages added:
-- `react-d3-tree@^3.6.2` - Tree visualization library
-
-### Existing dependencies leveraged:
-- `lucide-react` - Icons for UI controls
-- `axios` - API communication
-- `react` - Component framework
-
-## Testing Checklist
-
-- [ ] Run database migration
-- [ ] Create a new litter
-- [ ] Add puppies to litter via DogForm
-- [ ] Verify parent relationships auto-created
-- [ ] View pedigree tree for a dog with 3+ generations
-- [ ] Test zoom/pan controls in pedigree view
-- [ ] Add dog with manual parent selection
-- [ ] Edit existing dog and change litter assignment
-- [ ] Delete litter and verify puppies remain (litter_id set to NULL)
-
-## Future Enhancements
-
-1. **Litter Dashboard:**
-   - Visual cards for each litter
-   - Photos of puppies
-   - Whelping countdown
-
-2. **Enhanced Pedigree Features:**
-   - Print to PDF
-   - Color coding by health clearances
-   - COI display on tree nodes
-   - Descendant tree (reverse pedigree)
-
-3. **Batch Operations:**
-   - Add multiple puppies at once
-   - Bulk photo upload for litter
-   - Auto-naming scheme (Litter Letter + Name)
-
-4. **Analytics:**
-   - Average litter size by pairing
-   - Color distribution predictions
-   - Genetic diversity metrics
-
-## Migration Path
-
-### From Current System
-
-1. Pull feature branch
-2. Run migration: `node server/db/migrate_litter_id.js`
-3. Install dependencies: `cd client && npm install`
-4. Restart server
-5. Existing dogs remain unchanged
-6. Start creating litters for new puppies
-
-### Rollback Plan
-
-If issues arise:
-1. The `litter_id` column can remain NULL
-2. System continues to work with manual parent selection
-3. No data loss occurs
-4. Simply don't use litter feature until fixed
-
-## Architecture Decisions
-
-### Why litter_id Column?
-
-**Considered alternatives:**
-1. ✗ Bridge table `litter_puppies` - Adds complexity, same result
-2. ✗ JSON array in `litters.puppy_ids` - Poor query performance
-3. ✓ **Foreign key in dogs table** - Simple, performant, standard pattern
-
-### Why Radio Button Toggle?
-
-**User Experience:**
-- Clear visual distinction between modes
-- Prevents accidental litter/manual mixing
-- Familiar UI pattern
-- Easy to understand for non-technical users
-
-### Why react-d3-tree?
-
-**Alternatives evaluated:**
-- D3.js directly - Too much custom code required
-- vis.js - Not React-friendly
-- react-family-tree - Less flexible
-- **react-d3-tree** - ✓ React-native, customizable, maintained
-
-## Performance Considerations
-
-1. **Pedigree Loading:**
-   - Recursive queries limited to 5 generations
-   - Indexes on `parents` table ensure fast lookups
-   - Tree data cached in component state
-
-2. **Litter Queries:**
-   - New index on `dogs.litter_id` enables fast filtering
-   - Puppy counts calculated efficiently via JOIN
-
-3. **Frontend Rendering:**
-   - React-d3-tree uses virtual DOM for smooth updates
-   - Lazy loading prevents rendering off-screen nodes
-
-## Security Notes
-
-- All parent/litter relationships validated server-side
-- Gender validation prevents invalid pairings
-- Foreign key relationships ensure referential integrity
-- SQL injection prevented via parameterized queries
-
-## Contributing
-
-When extending these features:
-
-1. **Backend changes:** Update `server/routes/litters.js`
-2. **Frontend forms:** Modify `client/src/components/LitterForm.jsx` or `DogForm.jsx`
-3. **Visualization:** Edit `client/src/components/PedigreeView.jsx`
-4. **Database:** Create new migration file following naming convention

-# Frontend Fix Required: Add Dog Form
-
-## Problem
-
-The database and API are correct, but the **Add Dog frontend form** is still trying to use old `sire`/`dam` column names.
-
-## Error Details
-
-Server logs show migration completed successfully:
-```
-[Validation] ✓ Dogs table has no sire/dam columns
-[Validation] ✓ Parents table exists
-```
-
-But when adding a dog, you still get the "no such column: sire" error.
-
-## Root Cause
-
-The frontend `DogForm` or `AddDogModal` component is sending:
-- `sire` and `dam` (wrong)
-
-But the API expects:
-- `sire_id` and `dam_id` (correct)
-
-## Files to Fix
-
-Look for these files in `client/src/`:
-- `components/DogForm.jsx`
-- `components/AddDogModal.jsx`
-- `components/EditDogModal.jsx`
-- `pages/DogManagement.jsx`
-
-Or any component that has the Add/Edit Dog form.
-
-## The Fix
-
-### 1. Check Form State
-
-Look for state variables like:
-```javascript
-const [formData, setFormData] = useState({
-  name: '',
-  breed: '',
-  sex: '',
-  sire: '',  // ❌ WRONG - should be sire_id
-  dam: '',   // ❌ WRONG - should be dam_id
-  // ...
-});
-```
-
-**Change to:**
-```javascript
-const [formData, setFormData] = useState({
-  name: '',
-  breed: '',
-  sex: '',
-  sire_id: null,  // ✅ CORRECT
-  dam_id: null,   // ✅ CORRECT
-  // ...
-});
-```
-
-### 2. Check Form Submission
-
-Look for the API call:
-```javascript
-const response = await fetch('/api/dogs', {
-  method: 'POST',
-  headers: { 'Content-Type': 'application/json' },
-  body: JSON.stringify({
-    name: formData.name,
-    breed: formData.breed,
-    sex: formData.sex,
-    sire: formData.sire,  // ❌ WRONG
-    dam: formData.dam,    // ❌ WRONG
-    // ...
-  })
-});
-```
-
-**Change to:**
-```javascript
-const response = await fetch('/api/dogs', {
-  method: 'POST',
-  headers: { 'Content-Type': 'application/json' },
-  body: JSON.stringify({
-    name: formData.name,
-    breed: formData.breed,
-    sex: formData.sex,
-    sire_id: formData.sire_id,  // ✅ CORRECT
-    dam_id: formData.dam_id,    // ✅ CORRECT
-    // ...
-  })
-});
-```
-
-### 3. Check Select Dropdowns
-
-Look for parent selection dropdowns:
-```jsx
-<select
-  value={formData.sire}  // ❌ WRONG
-  onChange={(e) => setFormData({ ...formData, sire: e.target.value })}  // ❌ WRONG
->
-  <option value="">Select Sire</option>
-  {males.map(dog => (
-    <option key={dog.id} value={dog.id}>{dog.name}</option>
-  ))}
-</select>
-```
-
-**Change to:**
-```jsx
-<select
-  value={formData.sire_id || ''}  // ✅ CORRECT
-  onChange={(e) => setFormData({ 
-    ...formData, 
-    sire_id: e.target.value ? parseInt(e.target.value) : null  // ✅ CORRECT - convert to number or null
-  })}
->
-  <option value="">Select Sire</option>
-  {males.map(dog => (
-    <option key={dog.id} value={dog.id}>{dog.name}</option>
-  ))}
-</select>
-```
-
-### 4. Check Edit Mode
-
-When editing an existing dog:
-```javascript
-// ❌ WRONG - trying to access old columns
-setFormData({
-  ...dog,
-  sire: dog.sire?.id || '',
-  dam: dog.dam?.id || '',
-});
-```
-
-**Change to:**
-```javascript
-// ✅ CORRECT - use correct field names
-setFormData({
-  ...dog,
-  sire_id: dog.sire?.id || null,
-  dam_id: dog.dam?.id || null,
-});
-```
-
-### 5. Check Litter Mode
-
-If the form has litter selection mode:
-```javascript
-if (useLitter && selectedLitter) {
-  dogData.sire = selectedLitter.sire_id;  // ❌ WRONG field name
-  dogData.dam = selectedLitter.dam_id;    // ❌ WRONG field name
-}
-```
-
-**Change to:**
-```javascript
-if (useLitter && selectedLitter) {
-  dogData.sire_id = selectedLitter.sire_id;  // ✅ CORRECT
-  dogData.dam_id = selectedLitter.dam_id;    // ✅ CORRECT
-}
-```
-
-## Quick Search & Replace
-
-In your frontend code, search for:
-
-1. **State initialization**: `sire: ''` → `sire_id: null`
-2. **State initialization**: `dam: ''` → `dam_id: null`
-3. **API payload**: `sire:` → `sire_id:`
-4. **API payload**: `dam:` → `dam_id:`
-5. **Form handlers**: `formData.sire` → `formData.sire_id`
-6. **Form handlers**: `formData.dam` → `formData.dam_id`
-
-## Testing After Fix
-
-1. Open Add Dog modal
-2. Fill in name, breed, sex
-3. Select a sire from dropdown
-4. Select a dam from dropdown
-5. Click Submit
-6. Should work without "sire column" error!
-
-## API Contract (For Reference)
-
-The server `POST /api/dogs` expects:
-```json
-{
-  "name": "string",
-  "breed": "string",
-  "sex": "male" | "female",
-  "sire_id": number | null,
-  "dam_id": number | null,
-  "litter_id": number | null,
-  "registration_number": "string" | null,
-  "birth_date": "YYYY-MM-DD" | null,
-  "color": "string" | null,
-  "microchip": "string" | null,
-  "notes": "string" | null
-}
-```
-
-## Why This Happens
-
-The database migration fixed the backend, but:
-- Frontend code wasn't updated to use new field names
-- Old form components still reference `sire`/`dam`
-- API expects `sire_id`/`dam_id` (correct)
-
-## Example Complete Fix
-
-Here's a complete example of a corrected form:
-
-```jsx
-import React, { useState, useEffect } from 'react';
-
-function DogForm({ dog, onSubmit, onCancel }) {
-  const [formData, setFormData] = useState({
-    name: '',
-    breed: '',
-    sex: 'male',
-    birth_date: '',
-    sire_id: null,  // ✅ CORRECT
-    dam_id: null,   // ✅ CORRECT
-    litter_id: null,
-    registration_number: '',
-    microchip: '',
-    color: '',
-    notes: ''
-  });
-
-  const [males, setMales] = useState([]);
-  const [females, setFemales] = useState([]);
-
-  useEffect(() => {
-    // Load existing dogs for parent selection
-    fetch('/api/dogs')
-      .then(res => res.json())
-      .then(dogs => {
-        setMales(dogs.filter(d => d.sex === 'male'));
-        setFemales(dogs.filter(d => d.sex === 'female'));
-      });
-
-    // If editing, populate form
-    if (dog) {
-      setFormData({
-        ...dog,
-        sire_id: dog.sire?.id || null,  // ✅ CORRECT
-        dam_id: dog.dam?.id || null,    // ✅ CORRECT
-        birth_date: dog.birth_date || '',
-        registration_number: dog.registration_number || '',
-        microchip: dog.microchip || '',
-        color: dog.color || '',
-        notes: dog.notes || ''
-      });
-    }
-  }, [dog]);
-
-  const handleSubmit = async (e) => {
-    e.preventDefault();
-

-
-## Summary
-
-✅ **Backend is correct** - Database and API use `sire_id`/`dam_id`
-❌ **Frontend needs update** - Forms still use `sire`/`dam`
-
-**Fix**: Replace all instances of `sire`/`dam` with `sire_id`/`dam_id` in frontend forms.

-## Common Workflows
-
-### Workflow 1: Breeding a Litter
-
-1. ✓ Select breeding pair (sire and dam)
-2. ✓ Create litter record with breeding date
-3. ✓ Track whelping date when puppies are born
-4. ✓ Add each puppy:
-   - Link to the litter
-   - Enter individual details
-   - Assign registration numbers
-5. ✓ View pedigree of any puppy to see full ancestry
-
-### Workflow 2: Recording Historical Dogs
-
-1. ✓ Add foundation dogs (no parents)
-2. ✓ Add their offspring using manual parent selection
-3. ✓ Continue building the family tree
-4. ✓ View pedigrees to verify relationships
-
-### Workflow 3: Planning a Breeding
-
-1. ✓ View pedigrees of potential sire and dam
-2. ✓ Check for common ancestors
-3. ✓ Use trial pairing tool (coming soon)
-4. ✓ Create litter when breeding occurs
-
----
-
-## Tips & Best Practices
-
-### For Litter Management
-
-✅ **Do:**
-- Create the litter record BEFORE adding puppies
-- Enter accurate breeding dates for record keeping
-- Use meaningful notes (progesterone timing, heat cycle info)
-- Link puppies to litters for automatic parent relationships
-
-❌ **Don't:**
-- Don't change sire/dam after litter creation (create new litter instead)
-- Don't forget to update whelping date when puppies arrive
-- Avoid mixing litter-linked and manually-parented puppies
-
-### For Pedigree Viewing
-
-✅ **Do:**
-- Zoom out to see the full tree at once
-- Use drag to focus on specific branches
-- Click nodes to see additional details
-- Reset view if you get lost
-
-❌ **Don't:**
-- Don't try to edit from pedigree view (use dog edit form)
-- Avoid excessive zooming (can make nodes too small)
-
-### Data Entry Tips
-
-1. **Registration Numbers**: Enter consistently (e.g., "AKC-12345")
-2. **Microchips**: Use full 15-digit number
-3. **Birth Dates**: Critical for age calculations and sorting
-4. **Breed Names**: Keep consistent spelling and capitalization
-5. **Colors**: Use standard color terminology for your breed
-

-
-## Troubleshooting
-
-### "No such column: sire" Error
-
-**Problem:** Getting this error when adding a dog
-
-**Solution:** 
-1. Make sure you ran the migration:
-   ```bash
-   node server/db/migrate_litter_id.js
-   ```
-2. Restart the server
-3. Try again
-
-### Pedigree Tree Not Loading
-
-**Problem:** Pedigree modal shows "Loading..." forever
-
-**Possible Causes:**
-- Dog has no parents recorded
-- Network issue
-- Server not running
-
-**Solution:**
-1. Check browser console for errors
-2. Verify server is running
-3. Ensure dog has at least one parent recorded
-
-### Parents Not Auto-Populating
-
-**Problem:** Selected a litter but parents didn't fill in
-
-**Solution:**
-1. Refresh the page
-2. Make sure litter has valid sire and dam
-3. Try selecting the litter again
-
-### Can't See All Generations
-
-**Problem:** Pedigree tree only shows 2-3 generations
-
-**This is normal if:**
-- Older generations don't have parents recorded
-- Foundation dogs have no ancestry
-- You need to add more historical data

 A reactive, interactive dog breeding genealogy mapping system for professional kennel management.
 
-## ⚠️ Important: Database Migration Required
+---
 
-**If you have an existing BREEDR installation**, you must run a migration to fix the microchip field constraint:
-
-```bash
-# Enter the container
-docker exec -it breedr sh
-
-# Run migration
-node server/db/migrate_microchip.js
-
-# Exit and restart
-exit
-docker restart breedr
-```
-
-**What this fixes:** The microchip field now allows multiple dogs without microchips (previously caused "UNIQUE constraint failed" errors).
-
-**See full details:** [docs/MICROCHIP_FIX.md](docs/MICROCHIP_FIX.md)
+## 🌟 Recent Highlights (v0.8.0)
+- **✅ Reverse Pedigree** — Toggle between ancestors and descendants view for full lineage tracking.
+- **✅ External Dog Mapping** — Assign parents to external dogs, allowing for full genealogy of outside lines.

-```
-
-Key dependencies:
-- `react-d3-tree`: ^3.6.2 - D3 tree visualization
-- `date-fns`: ^2.30.0 - Date formatting utilities
-- `d3`: ^7.9.0 - D3 core library
-
-### 2. Deploy the Branch
-
-```bash
-git checkout feature/enhanced-litters-and-pedigree
-git pull origin feature/enhanced-litters-and-pedigree
-```
-
-### 3. Restart the Application
-
-**With Docker:**
-```bash
-docker-compose down
-docker-compose up --build -d
-```
-
-**Without Docker:**
-```bash
-# Terminal 1 - Server
-cd server
-npm install
-npm run dev
-
-# Terminal 2 - Client
-cd client
-npm install
-npm run dev
-```
-
-### 4. Access the Pedigree
-
-Navigate to any dog and access the pedigree at:
-```
-http://localhost:5173/pedigree/:dogId
-```
-
-For example:
-```
-http://localhost:5173/pedigree/1
-```
-
-## Testing Checklist
-
-### Basic Functionality
-- [ ] Pedigree page loads without errors
-- [ ] Tree displays correctly for dogs with parents
-- [ ] Nodes show correct information (name, registration, birth year)
-- [ ] Colors are correct (blue=male, pink=female)
-
-### Interactive Controls
-- [ ] Zoom in button works
-- [ ] Zoom out button works
-- [ ] Reset button returns to default view
-- [ ] Mouse wheel zoom works
-- [ ] Click and drag panning works
-
-### Navigation
-- [ ] Clicking a node navigates to that dog's profile
-- [ ] Back to Profile button works
-- [ ] Generation selector changes displayed generations
-
-### Data Display
-- [ ] COI displays correctly with proper color
-- [ ] Pedigree completeness calculates accurately
-- [ ] Stats update when generation selector changes
-
-### Edge Cases
-- [ ] Handles dogs with no parents gracefully
-- [ ] Handles dogs with only one parent
-- [ ] Handles incomplete pedigrees
-- [ ] Shows appropriate message when no data available
-
-### Responsive Design
-- [ ] Works on desktop (1920x1080)
-- [ ] Works on tablet (768x1024)
-- [ ] Works on mobile (375x667)
-- [ ] Print view displays correctly
-
-## API Requirements
-
-The pedigree tree depends on these existing API endpoints:
-
-### Required Endpoints
-
-1. **GET `/api/pedigree/:id`** - Get pedigree tree
-   - Must return nested sire/dam objects
-   - Should include: id, name, sex, registration_number, birth_date
-   - Example response:
-   ```json
-   {
-     "id": 1,
-     "name": "Dog Name",
-     "sex": "male",
-     "registration_number": "ABC123",
-     "birth_date": "2020-01-01",
-     "sire": {
-       "id": 2,
-       "name": "Father Name",
-       "sex": "male",
-       "sire": { ... },
-       "dam": { ... }
-     },
-     "dam": {
-       "id": 3,
-       "name": "Mother Name",
-       "sex": "female",
-       "sire": { ... },
-       "dam": { ... }
-     }
-   }
-   ```
-
-2. **GET `/api/pedigree/:id/coi`** - Get COI calculation
-   - Returns coefficient of inbreeding
-   - Example response:
-   ```json
-   {
-     "coi": 3.125,
-     "generations": 5
-   }
-   ```
-
-## Known Limitations
-
-1. **Performance**: Very large pedigrees (>100 nodes) may experience slowdown
-2. **COI**: Calculation requires complete pedigree data
-3. **Mobile**: Tree may be difficult to navigate on very small screens
-4. **Print**: May require landscape orientation for best results
-
-## Future Enhancements (Not in Sprint 1)
-
-- [ ] PDF export functionality
-- [ ] Highlight common ancestors between two dogs
-- [ ] Show inbreeding loops visually
-- [ ] Ancestor search/filter
-- [ ] Save custom tree views
-- [ ] Share pedigree links
-- [ ] Printable certificate template
-
-## Troubleshooting
-
-### Tree Doesn't Display
-- Check browser console for errors
-- Verify API endpoint `/api/pedigree/:id` is working
-- Check that dog has parent data in database
-- Ensure dependencies are installed (`npm install`)
-
-### Zoom/Pan Not Working
-- Check that react-d3-tree is properly installed
-- Clear browser cache and reload
-- Try in different browser
-
-### COI Not Showing
-- Verify `/api/pedigree/:id/coi` endpoint exists
-- Check that pedigree has sufficient data (at least 3 generations)
-- COI may be null for incomplete pedigrees
-
-### Styling Issues
-- Ensure `PedigreeTree.css` is imported in component
-- Check that CSS variables are defined in main stylesheet
-- Clear browser cache
-

-## Microchip Field Fix Verification
-
-### ✅ Schema Files (All Correct)
-
-#### 1. Database Schema: `server/db/init.js`
-- [x] **Line 29:** `microchip TEXT,` (no UNIQUE constraint)
-- [x] **Lines 38-43:** Partial unique index created
-  ```sql
-  CREATE UNIQUE INDEX IF NOT EXISTS idx_dogs_microchip 
-  ON dogs(microchip) 
-  WHERE microchip IS NOT NULL
-  ```
-
-**Status:** ✅ Correct for future installations
-
----
-
-#### 2. UI Form: `client/src/components/DogForm.jsx`
-- [x] **Line 150:** Microchip input has NO `required` attribute
-- [x] Label shows "Microchip Number" (no asterisk)
-- [x] Field is truly optional in the UI
-
-**Status:** ✅ Correct - users can leave microchip blank
-
----
-
-#### 3. Migration Script: `server/db/migrate_microchip.js`
-- [x] Exists and is executable
-- [x] Safely migrates existing databases
-- [x] Idempotent (can run multiple times)
-- [x] Preserves all data during migration
-
-**Status:** ✅ Available for existing installations
-
----
-
-#### 4. Migration Helper: `migrate-now.sh`
-- [x] Shell script for easy execution
-- [x] Checks if container is running
-- [x] Runs migration inside container

-## For Future Installations
-
-### Fresh Install (No Migration Needed)
-
-When a user does a **fresh install** (no existing database):
-
-1. Container starts
-2. `server/db/init.js` runs automatically
-3. Database created with **correct schema**
-4. Microchip field is **optional from the start**
-5. No migration required ✅
-
-### Existing Installation (Migration Required)
-
-When a user **upgrades** from an old version:
-
-1. Pull latest code
-2. Rebuild Docker image
-3. Start container
-4. **Must run migration:** `docker exec -it breedr node server/db/migrate_microchip.js`
-5. Restart container
-6. Microchip field now optional ✅

-## Testing Checklist
-
-### Test 1: Add Dog Without Microchip
-```bash
-curl -X POST http://localhost:3000/api/dogs \
-  -H "Content-Type: application/json" \
-  -d '{"name":"TestDog1","breed":"Lab","sex":"male"}'
-```
-**Expected:** ✅ Success (201 Created)
-
-### Test 2: Add Multiple Dogs Without Microchips
-```bash
-curl -X POST http://localhost:3000/api/dogs \
-  -H "Content-Type: application/json" \
-  -d '{"name":"TestDog2","breed":"Lab","sex":"female"}'
-```
-**Expected:** ✅ Success (multiple NULL values allowed)
-
-### Test 3: Add Dog With Microchip
-```bash
-curl -X POST http://localhost:3000/api/dogs \
-  -H "Content-Type: application/json" \
-  -d '{"name":"TestDog3","breed":"Lab","sex":"male","microchip":"123456789"}'
-```
-**Expected:** ✅ Success
-
-### Test 4: Duplicate Microchip Should Fail
-```bash
-curl -X POST http://localhost:3000/api/dogs \
-  -H "Content-Type: application/json" \
-  -d '{"name":"TestDog4","breed":"Lab","sex":"female","microchip":"123456789"}'
-```
-**Expected:** ❌ Error (UNIQUE constraint still enforced for non-NULL)
-
----
-
-## Database Verification
-
-### Check Schema Directly
-
-```bash
-# Enter container
-docker exec -it breedr sh
-
-# Open SQLite CLI
-sqlite3 /app/data/breedr.db
-
-# Check table schema
-.schema dogs
-
-# Should show:
-# microchip TEXT,  (no UNIQUE)
-
-# Check indexes
-.indexes dogs
-
-# Should show:
-# idx_dogs_microchip (partial index)
-
-# Verify partial index
-SELECT sql FROM sqlite_master 
-WHERE type='index' AND name='idx_dogs_microchip';
-
-# Should show:
-# CREATE UNIQUE INDEX idx_dogs_microchip 
-# ON dogs(microchip) WHERE microchip IS NOT NULL
-```
-
----
-
-## Rollback Plan
-
-If something goes wrong:
-
-### Option A: Restore Backup
-```bash
-docker stop breedr
-cp /mnt/user/appdata/breedr/breedr.db.backup \
-   /mnt/user/appdata/breedr/breedr.db
-docker start breedr
-```
-
-### Option B: Re-run Migration
-```bash
-docker exec -it breedr node server/db/migrate_microchip.js
-docker restart breedr
-```
-
-### Option C: Fresh Database (Data Loss)
-```bash
-docker stop breedr
-rm /mnt/user/appdata/breedr/breedr.db
-docker start breedr
-```
-
----
-
-## Deployment Verification
-
-After deploying to production:
-
-- [ ] Check container logs for schema initialization
-- [ ] Verify database schema with SQLite CLI
-- [ ] Test adding dog without microchip via UI
-- [ ] Test adding dog with microchip via UI
-- [ ] Confirm no UNIQUE constraint errors
-- [ ] Verify partial index exists
-- [ ] Test duplicate microchip still fails
-
----
-
-## Common Issues
-
-### Issue: Still Getting UNIQUE Constraint Error
-
-**Cause:** Migration not run on existing database
-
-**Solution:**
-```bash
-docker exec -it breedr node server/db/migrate_microchip.js
-docker restart breedr
-```
-
-### Issue: Migration Script Not Found
-
-**Cause:** Old code still in container
-
-**Solution:**
-```bash
-cd /mnt/user/appdata/breedr-build
-git pull
-docker build -t breedr:latest .
-docker stop breedr && docker rm breedr
-# Recreate container with new image
-```
-
-### Issue: Microchip Required in UI
-
-**Cause:** Browser cached old JavaScript
-
-**Solution:**
-- Hard refresh: Ctrl+Shift+R (Windows/Linux) or Cmd+Shift+R (Mac)
-- Clear browser cache
-- Try incognito/private window
-
----
-
-## File Manifest
-
-### Core Files (Must Be Present)
-- ✅ `server/db/init.js` - Database schema (corrected)
-- ✅ `server/db/migrate_microchip.js` - Migration script
-- ✅ `client/src/components/DogForm.jsx` - UI form (microchip optional)
-- ✅ `migrate-now.sh` - Helper script
-- ✅ `docs/MICROCHIP_FIX.md` - Detailed documentation
-- ✅ `docs/VERIFICATION_CHECKLIST.md` - This file
-- ✅ `README.md` - Updated with migration notice
-
-### Validation Commands
-
-```bash
-# Check all files exist
-ls -la server/db/init.js

-ls -la docs/MICROCHIP_FIX.md
-ls -la docs/VERIFICATION_CHECKLIST.md
-
-# Verify microchip field in init.js
-grep -n "microchip TEXT" server/db/init.js
-# Should show line 29 with NO UNIQUE
-
-# Verify partial index
-grep -A2 "idx_dogs_microchip" server/db/init.js
-# Should show WHERE clause
-
-# Verify form has no required
-grep -n 'name="microchip"' client/src/components/DogForm.jsx
-# Should NOT have required attribute
-```
